Abstract

The resistive instability in double current sheet (DCS) systems with shear flows are explored by using a magnetohydrodynamic simulation method. The results showed that the linear growth rate of the antisymmetric and symmetric magnetic reconnection modes depend on the relative vicinity of the two current sheets. When the shear flows are strong and have velocities near or larger than the local Alfvén speed, the growth of the antisymmetric mode resistive instability in DCS systems is further increased. It is also found that the growth rate of the resistive instability decreases as the plasma beta increases.
